The invention discloses a hoisting device for motor maintenance, and belongs to the field of motor maintenance. The hoisting device comprises a maintenance platform, vertical columns, a top plate, twooppositely-arranged hydraulic cylinders, two connecting blocks, two oppositely-arranged air cylinders, two clamps, an oil tank, an oil pump, a one-way valve, a synchronous motor, a two-way overflow valve and an unloading valve. According to the hoisting device for motor maintenance, the clamps are arranged at the positions of piston columns of the air cylinders, a motor is clamped by the to oppositely-arranged clamps, then the two oppositely-arranged hydraulic cylinders move the connecting blocks connected with the air cylinders up and down, and therefore up-and-down movement of the motor isachieved. The air cylinders are oppositely arranged, the stability is achieved when the motor is clamped by the clamps, and the large motor can be hoisted. The two hydraulic cylinders supply oil through the two-way overflow valve and the synchronous motor, the hydraulic oil entering the two hydraulic cylinders is synchronous, the oil pressure is consistent, thus, the motor is more stable in the rising process, and damage caused by unstable operation in the motor maintenance process is reduced.
本发明公开了一种电机维修用起吊装置,属于电机维修领域,包括维修平台、立柱、顶板、相对设置的两个液压缸、两个连接块、相对设置的两个气缸、两个夹子、油箱、油泵、单向阀、同步马达、双向溢流阀、以及卸荷阀。本发明公开的一种电机维修用起吊装置,气缸活塞柱处设有夹子,相对设置的两个夹子夹住电机,然后相对设置的两个液压缸上下移动与气缸连接的连接块,从而实现电机的上下运动。气缸相对设置,使夹子夹住电机时比较稳定,可以对大型电机进行起吊。两个液压缸通过双向溢流阀和同步马达供油,使得进入两个液压缸内的液压油同步、而且油压一致,从而使电机在上升过程中更加平稳,减少了电机维修过程中因操作不平稳而造成的损伤。
